Implement RSI(14) indicator in PHP

I am looking for a freelancer who can implement the RSI(14) indicator in PHP for a standalone project.

E.g, these are the closes prices of SPY symbol till 2023.11.03:
array (size=14)
0 => float 436.02
1 => float 430.21
2 => float 426.43
3 => float 421.19
4 => float 420.46
5 => float 423.63
6 => float 417.55
7 => float 412.55
8 => float 410.68
9 => float 415.59
10 => float 418.2
11 => float 422.66
12 => float 430.76
13 => float 434.69

RSI(14) should be 58.17.

You can see closes prices and RSI value:
